IPO allocations in Australia are split into three main tranches: institutional, sophisticated investor (s708), and retail. Institutional investors have historically received around 90% of available shares. Retail applicants face scale-back in popular deals. Investors who qualify under Section 708 of the Corporations Act access a separate tranche with distinct advantages, often before the public offer opens.
Most investors assume an IPO is open to anyone who applies. Submit your application, transfer your money, and wait. That is how it looks on paper.
That is not how it works in practice.
IPO allocation in Australia is a structured, tiered process controlled by the company raising capital and its lead manager. Understanding how it works is not just useful knowledge. It is the difference between getting shares and missing out entirely.
What Is IPO Allocation in Australia?
IPO allocation is the process by which a company and its advisers decide who receives shares, and how many, after an offer closes. It is not first-in-first-served. It is not random. The lead manager and company have significant discretion over who gets stock.
When a company lodges its prospectus with ASIC, it opens an offer period for investors to apply for shares. Once that period closes, the bookbuild is finalised and allocation decisions are made before shares are listed on ASX. Applications are assessed, shares are distributed across investor categories, and then the company is admitted to the official ASX list.
The Prospectus and the Offer Period
Every Australian IPO that targets retail investors must include a prospectus. This document, which often exceeds 100 pages, outlines the company, its financials, its risks, and the terms of the offer. ASIC reviews the prospectus before the offer can open to the public.
The offer period typically runs for several weeks. During this time, investors submit applications and transfer application money.
What Happens When the Books Close
Once the offer closes, the company and its lead manager confirm allocations. If an IPO is oversubscribed, meaning applications exceed available shares, your application may be subject to scale-back. You may receive fewer shares than you applied for, or none at all.
This is where the structure of the allocation system matters most.
How Are IPO Shares Divided Between Investor Types?
IPOs in Australia are typically split into two or three tranches: the institutional bookbuild, the sophisticated investor offer (structured under Section 708 of the Corporations Act), and the retail public offer. Historically, institutional investors receive around 90% of IPO shares, with retail investors sharing the remaining portion.
That 90/10 split is not set by regulation. It is the result of how the bookbuild process works in practice, and why the type of investor you are determines the access you get.
The Institutional Bookbuild
The institutional tranche comes first. Before the retail offer opens, the lead manager runs a bookbuild with institutional investors: fund managers, superannuation funds, and other large-capital entities. These investors indicate demand and bid at their preferred price.
This process often happens while the company is still on a trading halt. By the time the public knows a raise is happening, the institutional allocation is frequently already locked in.
The Sophisticated Investor Tranche (s708)
Some IPOs include a separate tranche specifically for sophisticated investors under Section 708 of the Corporations Act. This is not the retail public offer. It is a distinct offer that operates without the full disclosure requirements of a prospectus, reserved for investors who meet specific financial thresholds.
Sophisticated investors in this tranche may access shares at pricing that is separate from the retail offer, and in some cases participate in pre-IPO rounds at a discount to the eventual IPO price.
The Retail Public Offer
The retail offer is what most investors see when a prospectus is published. Any eligible investor can submit an application via the prospectus form or through their broker. This tranche typically represents a smaller portion of the total raise.
Retail investors share whatever is not absorbed by the institutional and s708 tranches.
What Happens When an IPO Is Oversubscribed?
An oversubscribed IPO occurs when total applications exceed the number of shares available. In popular deals, the retail tranche is often significantly oversubscribed, which triggers scale-back. Your allocation is reduced proportionally, or in heavily subscribed offers, you may receive nothing at all.
This is not an edge case. The weighted average return of 2024 ASX IPOs was 23.4%, well above broader market returns that year. Guzman y Gomez (ASX:GYG), which listed in June 2024, rose 84.4% across its first year of trading. Demand for deals like that is fierce, and retail allocations shrink accordingly.
Understanding the full picture of IPO risks in Australia before applying is essential. Oversubscription is a feature of desirable deals, but it cuts directly into your allocation.
How Allocation Decisions Are Actually Made
The lead manager and the company have significant discretion over who receives shares. This discretion is not arbitrary, but it is not fully transparent either.
Allocation decisions favour investors who are likely to hold their position rather than sell immediately on listing. Investors who flip shares on day one to capture the listing premium are not welcome participants. Lead managers track this behaviour and deprioritise known flippers in future deals.
ASX placements operate on the same principle. Relationship capital matters. Investors who have participated in previous deals with a particular broker, demonstrated commitment, and built a track record of holding positions tend to receive better allocations over time.
If you do not have an existing relationship with a broker running a bookbuild, you are competing with everyone else in the retail tranche for a small slice of what remains after institutional and s708 investors have been served.
What Do Sophisticated Investors Get That Retail Investors Don’t?
Sophisticated investors who qualify under Section 708 of the Corporations Act access a different tier of the IPO market entirely. This includes participation in pre-IPO rounds, dedicated s708 tranches within IPOs, and placement opportunities that are never offered to the retail public.
A pre-IPO investment is structured at a discount to the eventual IPO price. The trade-off is reduced liquidity and less formal documentation. But for investors with the risk tolerance and financial capacity to participate, it represents entry at a valuation that the public never sees.
To qualify, you need to meet at least one of the following thresholds under Section 708(8) of the Corporations Act:
- Net assets of at least $2.5 million, or
- Gross income of at least $250,000 per year in each of the last two financial years.
You also need a current qualified accountant certificate issued within the past two years confirming that you meet one of those thresholds.
Once certified, you can access ASX IPO opportunities that are structured specifically for s708 investors. These deals operate outside the prospectus disclosure regime, which means they move faster and with fewer public restrictions on the raise process.

The State of Australia’s IPO Market in 2025 and 2026
After a challenging few years, the Australian IPO market recovered meaningfully in 2025. ASX saw 92 total listings across the year, with three companies debuting at $1 billion-plus market capitalisations: Greatland Resources, Virgin Australia, and GemLife. Each raised more than $400 million at IPO.
For context, 2024 had seen the lowest listing volumes in two decades despite $4.1 billion in total funds raised. The market was bifurcated: a handful of blockbuster listings alongside difficult conditions for smaller companies.
What does this mean for investors in 2026? Competition for allocation in quality deals is intensifying. As the pipeline of prospective listings grows, so does investor demand for the best opportunities. Getting access before the retail offer opens, through the right broker and the right investor classification, becomes more important, not less.
How to Improve Your Chances of Getting an Allocation
The most direct path to better IPO allocations is working through a broker with direct access to deal flow. This means a broker who is actually involved in the bookbuild, not just distributing shares from whatever is left in the retail tranche.
It also means being the right kind of investor. Brokers allocate shares to clients who hold positions, participate regularly, and add value to the register. That track record takes time to build, but it compounds.
And if you qualify as a sophisticated investor under Section 708, make sure your accountant certificate is current and that you are registered with a platform that provides access to s708-only deals. The retail public offer is the last tranche filled. The investors who access the market earlier, at better terms, built that access deliberately.
Conclusion
IPO allocation in Australia is not democratic. Institutional investors receive the majority of shares. Sophisticated investors under s708 access dedicated tranches with distinct advantages. Retail investors receive what remains, and in popular deals, that can be very little.
Understanding the structure is the first step. Positioning yourself correctly within it is the next.
If you qualify as a sophisticated investor, register with a dedicated broker at 708 Deals to access ASX IPO allocations directly through a senior stockbroker who notifies you before the public offer opens.
Frequently Asked Questions
Can retail investors apply for IPO shares in Australia?
Yes. Retail investors can apply for shares via the prospectus during the public offer period. However, the retail tranche represents a smaller portion of the total raise. In oversubscribed deals, retail applicants often receive fewer shares than they applied for, or none at all, through a process called scale-back.
What is scale-back in an Australian IPO?
Scale-back occurs when an IPO receives more applications than there are shares available, making it oversubscribed. When this happens, the company and its advisers reduce individual allocations proportionally. In heavily oversubscribed deals, some applicants receive nothing and have their application money refunded.
How do sophisticated investors get better IPO allocations?
Sophisticated investors who qualify under Section 708 of the Corporations Act can access a dedicated tranche within certain IPOs that is not available to the retail public. They may also participate in pre-IPO rounds structured at a discount to the final IPO price. This access requires a current qualified accountant certificate and registration with a broker who handles s708 deal flow.
What is the institutional tranche in an ASX IPO?
The institutional tranche is the portion of an IPO reserved for fund managers, superannuation funds, and other large institutional investors. The lead manager runs a bookbuild with these investors before the retail offer opens. Historically, institutional investors receive around 90% of all IPO shares across the tranches.
How do I qualify as a sophisticated investor in Australia?
To qualify under Section 708(8) of the Corporations Act, you must meet at least one of two financial thresholds: net assets of at least $2.5 million, or gross income of at least $250,000 per year in each of the previous two financial years. You must obtain a certificate from a qualified accountant confirming you meet the criteria. The certificate must be no more than two years old at the time of each investment.
